By providing a digital video memory arrangement with first and second address generating means, digital video signals can be written at a first location of a non-mechanical memory and (almost) immediately read out from a second location of the non-mechanical memory, with the reading out both being capable of featuring backward and forward jumps. As a consequence of a coupling between the first and the second address generating means it becomes impossible to, on the one hand, unjustly pass with jumping in the read signal the running or stopped write signal and, on the other hand, unjustly pass with the running read signal the stopped write signal. To this end the second address generating means dispose over determining means for determining, in response to at least the write signal and the read signal, a permitted address jump. <MATH> |
